Railway Hollow Axle

The hollow design of a railroad axle is one of the most effective methods to reduce the weight of a railway axle. However, the conventional railway hollow axle has the limitation of a lightweight design because it has the same bore diameter along the axial position.

The new type of railway axle, the tapered inner surface railway axle, has a different inner diameter between the journal bearing seat and wheel seat.

This design method is one way to increase the weight reduction possibility. The purpose of the present study is to establish and evaluate the design of the tapered inner surface railway axle.

The case study and Finite Element Method (FEM) are applied to evaluate the strength of the lightweight railway axle according to the European Norm (EN 13103). Finally, the best design case for reducing the weight of the axle is drawn from the results of the case study.
